ABSTRACT:
Multiple-needle sewing machines are equipped with at least one needle bar and with fixing device for the individual needles as well as with at least one looper shaft to which the looper holder with the loopers is fixed. In order to obtain quick and easy changeover of a multiple-needle sewing machine to different sewing patterns on a large area sewing material it is proposed that manually operated quick-locking means are provided between each needle or a needle holder for each needle and the needle bar and/or between the looper holder of each looper or each looper and the looper shaft.
